TAS aural alerts will be muted when GPS altitude

Check to ensure the fuel selector is on the proper (normally fullest)
tank and that the seat backs are erect, wilh the seals adjusted and locked
in position. The seat belts and shoulder harness should be fastened and
adjusted and the inertia reel checked.
The mixture control should be kept in full RICH position to ensure
maximum acceleration if it should be necessary to open the throttle again.
Alternate aiJ should be closed unless there is an indication of induction
system icing, since the use of alternate air causes a reduction in power which
may be critical in case of a go-around. Full throttle operation with alternate
air open can cause detonation.
The amount of flap used during landings and the speed of the aircraft at
contact with the runway should be varied according to the landing surface
and conditions of wind and airplane loading. It is generally good practice
to contact the ground at the minimum possible safe speed consistent with
existing conditions.
Nonnally, the best technique for short and slow landings is to use full
flap and enough power to maintain the desired airspeed and approach flight
path. Reduce the speed during the flareout and contact the ground close to
the stalling speed. After ground contact hold the nose wheel off as long as
possible. As the airplane slows down, gently lower the nose and apply the
brakes. Braking is most effective when flaps are raised and back pressure
is applied to the control wheel, putting most of the aircraft weight on the
main wheels. In high wind conditions, particularly in strong crosswinds, it
may be desirable to approach the ground at higher than nonnal speeds with
parlial or no flaps.
